I laminate a lot. I previously was using some other brand. I do not even remember the name because I bought it at the store and I bought what was cheapest. It seemed fine. I always buy several packs at a time so it took a long time to use up. Over time, I have almost stopped shopping at the store and buy everything online. This looked like a good price so I bought several of the 3mm thickness and one 5mm. I opened the 3mm and it turned out so thick and perfect that I checked the package to make sure that I had not inadvertently opened the 5mm. It was the 3mm! The quality is so much better than I have ever used before. Even my husband noticed the difference in quality! This is easy to use and turns out perfectly for me. I am super pleased. I will only use Scotch brand from now on. This was a good price for a superior product. I can’t wait to try the 5mm!
